I just bought FPV F6( 2010) Ute 2 weeks ago with 40K on the clock and when I drove it for the first week it had great low to mid range repsonse (smooth to Snappy Mid Range Punch ) now seems to have lost that punch in the mid range.I havent done anything different and using the same fuel ( Bp 98% oct ) as like last week. Is that normal? does anybody have idea's . The car has had no modifications ( still under Factory warranty ) ANy feed back would be great !! Kos
